T0 all 107mm it may concer/zy.'

' Be it known` that l, llfinnmi G. llrrirrn, a citizen ol the United titats oit fnnerica, and resident of .lloipiiaun in the county ot Grays l-larbor, in `the State oit llashingrton, have invented certain non and 4usefull-nr provenientewin Log Brinks, of which the iollowing' is a specification,reference being had to the accompanying drawing. Y

My invention relates to log' bunks, that is to say, to devices that are mounted transversely on a fiat ear and are provided at their opposite ends with movable checks, either ot which may be tripped from the opposite side of the ear so as to release `the logs carried by the bunks, by gravity brought 'to bear through a transverse inclination or dip olli thecar. 1

The objects ot my invention are4 to produce improvements in devices pt the class described, through which strength, simplic ity, economy ot construction, and Jjacility of operation may be obtained. i

lllhat constitutes my intention will be hereinaftery described in detail and succinctly set forth in the appended claims.

ln the accompanyingdrawing,

lfligure .l is a top plan view. with parts obscured in `dotted lin ot one toi-iu oi Vembodiln/.nit ol my invention as applied; to

ra. single bunk. rilheohocl at one end of the bunk is shown as elevated, and the one at the other end is shown asfdepressed.

Figure ll is a medial, loiinitudinahv u'tical section ot the subject matteroi" Figure l.

4Figure lll is a. section on the line llllll of Figure Il, lookingin thedireetion ot the arrows.

Figure IV is a View similartoligure lll, showing;r a. modification ot thewchocli sup porting and tripping: mechanism, the chock being` in said ligure shown in the supported position. f j

Figure V is a. top` plan View of ,one end of a bunk, showing themodiication illustrated in Figure lV. In this view, the chock supporting position is shown in lull lines, and in the ytripping position in dotted lines.

Referring to the numerals on the drawing, l and 2 indicate, respectively, side pieces of an oblong` hollow trame which constitutes the bed or bolster of one of my bunks. The side pieces l and 2 may `be made .ot any suitable form of metal as, for example, the plates shown provided with angular anges the transverseextent of thelist car-'to `which they are applicable, and their `distance apart, determined by `the `Width of the plate Ll, may be varied at will in the sound discretion of the builder. A i u The plate l terminates, at each' end," at a distance short of theiiull extent ofthe side pieces `l and 2 sutlieient toV operatively aeeommodate a ehocli `that substantially lills the space between the, side pieces, one `at each `end of the` plate il. `llachehocl is pivotally mounted upon a cross bolt .7, its knuckle 8 being `preteralily located in close but operativeproximity to the end of Vthe plate t. The end or. the chock; G opposite the end of the knuckle 8 bentin the `form ot Va kneabeloiv which the leg lddepends. Between lugis 11 that are provided uponthe end ot the side pieces l and 2, upon across `bolt l2, is pivotedfasupporter l5 which is adapted to be sjwunguponthe boltlQ in the path otthelefr l0, so asito `support the chock vin a position elevated above` thetop of ythe bunk as shown at the lett iny Figure Il, or'

to drop it below `.the top of `the bunk `as shown at the right in Figure Il. Uponthe removal olthe support -lor the leg l0, the chock drops, `with `pivotal action upon its bolt 7, until itsy downward swing is arrest-ed by obstruction. i Thefsweep ol" `the leg `10 isin close` approximation` to the cross bolt 12 so` that there is a minimum leverage imposed.v upon the supporter l5, `,While lity is `in 'the ehocle supporting' position.

As is Well understood inthe art relating to bunks, the checks, beingdesigned to dis# charge `their load through gravity `by depressiono one-end ofthe bunk, must be `oper.- i

ated iromithe upper end of thebun'l, that is to say, from :the end `remote fromthe dis,- char-'ge end of the bunk. `'lolthatj end, Iprefer to employ a. bell crank lever `16 pivoted at its angle, as indicated at 17, to the ange 3.

l I l f 1,424,330

The short end of the lever 16` is pivote-d, :is indicated at 18, to a link bar `19, whoscend opposite that indicated at 18 ispivoted as indicated at 9,0 toarollcrl' working in opposite oblong guide-ways 22 providedior it in the respectiveside pieces 1 and 2. The roller 21 is preferably provided at itsoppo site ends with heads'l by which it is conned within the gaide-ways122.V 'bracei rod 2d is secured, asl indicated at 25, to the link bar 1.9,*'and yis pivotally securethas iiidicated at 26, tothe roller 21. The co-oper`- tion oit-the link bai' 19and the,v brace roc imparts a'true movement tothe roller 21 in its guide-ways through manipulation of the 'bell crank ylever 16'.' in Figure l, onego-i' t-he levers16 isshown inposition to retract its roller`21 from underneath the sugporter 15 towhichvit lis appropriated, while theother is shown in position to hold its supporter in the horizontaler chock-supporting position. ln Figures lfto lll, inclusive, is shown vthe rollerv 21 as above describedV ln the remaining iigures, -l` `illustrate a modified meansfor sustainingthe supporter'l.` In tlio'seflastunamed igures() indicates rod, pivoted at Vone end toabraclet ll10n one side piece of thebunlr, aiidhaviiig its' other end extending through `a slot similar lto 22 inFigure ll in the other side piece, within which it mayoscillate, between limits-lined by the length of vthe slot, under impulse iin'- parted through a member equivalent to the link bar 19. The rod'BO preferably car-` ries a roller or buffer 83 upon which, `when the rod 3G is disposedat right angles to the bunk sides land 2, as shown inl -lull vlines in- Figure V, the'fsupporter vlfis sustained in horizontal position, but which, when `the rod is swung upon its'braclzet 3l asshownin dotted lines in FigurevV, releases the supporter 15' and allows it to drop to the vertical.

. The operation of my device will be readily understood by oneslrilled in the art from' the "briet `description i thereof which follows.

Assuming that.. a flat car, lnot shown, is equipped with mybunlrs, disposed inpairs, they are supposed tolcarry a load of logs laid across thennlengthwise ofthe car, the logs `bein-g heldin place on the bunks by the chocls 6 which are in the elevated position shown at'the left inFigui-e Il; It now the caribe tiltedto onesidel or the other, the` logs v'will ten'dby gravity to roll ott the bunks, and may do so-when the lowermost chocks are tripped, an operation that may be accomplishedbypulling out the long arms of the levers 16 whi'chcontrolsaid checks, and which, asfhas been already specified, are disposed upon the uppermost side oi the car, outof-the way of danger to an" operator iby the"` released logs. fitter `each:v ,chock tripping operation, upon discharge of *the loes `the chock is av'ain set b i hand.; and the t; 9 n J l bunk is again ready for service.
